My experience with spray tans are limited to Bronze Baxx and now Sundrops, and Sundrops blows the spray tan experience out of the water.
My favourite part of the spray tan at Sundrops was that they use their own formula, which allows for a more natural colour IMO (I have pale skin so I fear the 'too dark' tan) and the bonus is that is seems to dry much quicker than other formulas. In past experiences, I have had to stand in front of a fan to dry off, followed by a few minutes in a tanning bed to really set it. At Sundrops, you can get dressed immediately.
What puts the experience over the top is the staff, and in my case, Laura. She was friendly, polite and professional, making me feel very comfortable and like I was in good hands.
Will only be going to Sundrops for spray tans from now on and highly recommend it!
